New blog post: How We Avoided $120K/Month in Observability Costs Our Datadog bill was $40K/mo and headed to $120K as we scaled. We replaced it with self-hosted Grafana LGTM stack for $15-18K/mo. The real lesson: per-GB SaaS pricing is a trap at scale. We went from 1TB/day to 6TB/day and our self-hosted costs barely moved. Datadog would have gone from $40K to $120K+. Self-hosting isn't just about sovereignty — sometimes the economics leave you no choice. Full write-up with architecture and timeline:

How We Avoided $120K/Month in Observability Costs | Rajesh Medampudi

Datadog was costing us $40K/month at 1 TB/day. We were growing to 6 TB. Instead of scaling the bill, we built our own platform that ran 8× cheaper...

My Bitcoin self-custody architecture: Layer 1: Hardware wallet — keys never touch the internet Layer 2: 2-of-3 multisig — no single point of failure, geographically distributed Layer 3: Own node — full verification, no third-party trust Same engineering principles as infrastructure architecture: Eliminate single points of failure Own your data Verify, don't trust After FTX, BlockFi, Celsius — the case for self-custody writes itself. Not your keys, not your coins. #bitcoin #selfcustody #sovereignty #nostr

🚨 Just published my first blog post — and it's about the number that stopped a leadership meeting cold. We were a gaming company scaling fast. 100K concurrent players. Infrastructure costs climbing 15% month over month. And the biggest line item wasn't compute or databases — it was observability. Datadog at 1TB/day: $40K/month. Projecting to 6TB/day: $120K/month. So we built our own platform for $1,500/month instead. In the post, I walk through: → How tagging AWS resources revealed waste we didn't know existed → Why we replaced Datadog + CloudWatch with a self-hosted LGTM stack (Loki, Grafana, Tempo, Mimir) → The surprising architectural change that cut cross-AZ transfer costs and improved reliability → What I'd do differently — and the question every engineering team should ask before signing a per-GB vendor contract If your observability bill is growing with your data volume, you might want to read this before the curve catches up with you. #AWS #Observability #CostOptimization #Grafana #Datadog #Kubernetes #Engineering View article →

Hey Nostr 👋 I'm Rajesh — platform engineer, 17+ years building distributed systems. What I've built: • Observability platforms processing 6TB/day at 85% below SaaS costs • Saved $120K/month on AWS for a gaming platform with 100K+ concurrent players • Infrastructure serving 100K+ concurrent users in real-time What I'll post here: • Technical deep dives (AWS, K8s, observability, self-hosting) • Building in public — shipping, breaking, learning • Bitcoin & sovereignty — running my own node, relay, and media server • Long-form articles via kind:30023 I run my own Nostr relay (nostr.onbitcoinstandard.com), Blossom media server (media.medampudi.com), and my blog pulls content directly from Nostr at build time.

Build your own seed signer, you don't need to buy anything from them. No secure element for seed signer for sure. The rest all are addressed with it.
